Care Guide

Watering

Keep soil consistently moist during active growth and flowering; avoid waterlogging

Fertilization

Apply balanced slow-release fertilizer at planting and when shoots emerge. Use low-nitrogen fertilizer to promote bulb health rather than excessive foliage growth

Eggshell powder topdress:Crush fully dried eggshells into fine powder; sprinkle lightly on soil surface at planting time; avoid direct contact with bulbs to prevent irritation
Pruning
  • Deadhead spent blooms to prevent self-seeding (optional, as plants naturalize well)
  • Remove yellowing foliage once fully browned to reduce fungal disease risk
  • Divide overcrowded bulb clumps every 3–4 years in autumn to maintain flowering vigor
